Description
Technical field
The field of the invention is the field of gaseous state effluent taste removal (d é sodorisation).More specifically, the present invention relates to, in this reactor, in the presence of washing lotion, make this effluent process by the technology of reactor with the taste removal of gaseous state effluent.
Background technology
At present, traditionally in may being equipped with or not being equipped with the vertical or horizontal tower of filler by from air, removing the scent of compound based on the chemical washing of acid, alkali and/or oxidant.
Although this processing method provides good result so far aspect effectiveness, but still have the operating cost problem, particularly also have no talent successfully solve with the relevant problem of floor space (emprise ausol).
This be because, utilize such equipment effectively to handle necessary time of contact (greater than second, consider the liquid-vapor interface exchange area that is generated) cause constructing large-sized engineering, promptly several meters high tower this means high material and civil engineering cost.
Used static mixer to study another solution for example to remove hydrogen sulfide (P é culier, 1996) and to make the processing unit of scent of gas.
Static mixer be used for traditionally improving liquid/liquid mixes or gas in the dispersion of liquid (main liquid phase).They for example are used in the chemical industry (dilution of solvent, the emulsification of non-miscible liquid etc.), in petroleum industry (mixing of the gasoline of different indexes, the mixing of additive and fuel etc.), paper industry (bleaching), food industry (interpolation of colouring agent, emulsifying agent) or the water treatment (rapid mixing of coagulation additives).
In the gas/liquid application, liquid phase is a principal phase with respect to gas phase usually, and gas phase is less important phase (promptly by injecting air with the water oxidation).
The major advantage of static mixer is as follows:
-low owing to not existing the mobile machine parts to safeguard;
-low volume;
-owing to mixing, good both macro and micro has good uniformity (not having the dead band usually);
The working flow scope of-Gao;
-wide fluid viscosity scope;
-strong heat exchange and mass exchange;
-operation easily.
But the major defect of these two-phase contactors is the high pressure loss that they produce (can than observed high 100 times in packed column).This pressure loss causes realizing higher draught capacity, therefore improves operating cost, and makes these contactors handle in the application incompatible at many industrial gasses.
Especially, the static mixer that comprises the screw element with three blades is known.Radial serrations on the wheel hub surface of each element can be adjusted to the position of the most suitable laminar flow, turbulent flow or intermediate flow.The assembly of seven elements forms the impeller that makes 180 ° of rotations of fluid.
The static mixer that comprises the screw element of placing with 90 ° of sequences also is known, and these elements are shunted separately repeatedly to obtain homogeneous mixture after several elements.
According to another type of static mixer, screw element is divided into fluid continuously and the series of 180 ° of rotations that replace.
According to a type again of static mixer, the stacked graining board of stratification forms the open channel that intersects, and next element and last element are 90 ° of placements.Fill in this and comprise dihedral vane and fluid is divided into a plurality of little threads,, produce fluid mixture thus their reorganization branch of laying equal stress on.
Whatsoever known static mixer, mixing and/or the high pressure loss that transfering part produced have constituted technology barrier all the time.Therefore, almost do not have the researcher to seek to be used for fluid-mixing industrial use in addition, and few trial reduces these pressure losses so that its operation optimization.
Therefore seem to attempt when keeping this system's miniaturization benefit, to solve these pressure loss problems, or find out the advantage that keeps static mixer but impeccable new solution.
Summary of the invention
The present invention is intended to overcome the shortcoming of prior art especially.
More specifically, the invention is intended to propose combine the technology that is used to handle scent of gas of the advantage of packed column and static mixer, promptly have the method that the low pressure loss (perte de charge) and high scent of compound are removed efficient.
The present invention also is intended to provide and compares this technology with low volume with the prior art solution.
The present invention also is intended to provide and compares this class technology that can reduce operating cost with the cost of known technology.

Thus, the present invention proposes than static mixer " ventilation " structure more.The bump that the fluid of this net is passed in circulation causes strong turbulence.But it can not cause the high pressure loss, and this is because cause with its relative low contact surface that flows.
This structure can be divided into fluid a plurality of shuntings, then they is mixed again.By changing VELOCITY DISTRIBUTION (fluid cut apart in succession and recombinate), this structure can redistribute fluid sleeve pipe (enveloppe) in, the generation strong turbulence, and well mixture also improves the interface exchange area.
This interfacial area is a key parameter, shifts and is eliminated this liquid phase to reactive liquid phase from gas phase because it influences pollutant.Because strong mixing the, so transfer ratio height, turbulent flow is also high.
Therefore the present invention can overcome the technology barrier of the high pressure loss that is produced by static mixer.
Compare with the air treatment system that uses traditionally, the gain aspect the pressure loss makes it possible to the blower fan (ventilateurs) that uses power lower, and this has significantly reduced operating cost; Energy consumption is actually capital cost item in the taste removal unit (running cost about 20%).
Compare with the scrubbing tower of prior art, device of the present invention can be made very small-sizedly, makes it become more easy-to-use system thus.
Have a plurality of industrial sites that the flavor source of gaseous emission is arranged, it can for example be installed in the position that each will handle smell, has avoided thus contaminated air is sent to the required any ventilation shaft network of center processing unit (for example scrubbing tower).Because the length of required ventilation shaft reduces, therefore the gain aspect equipment cost is significant.
